The Pro Football Hall of Fame's Class of 2015 gets inducted on Saturday. Shutdown Corner will profile the eight new Hall of Famers over the next week looking at each of their careers and their impact on the game. Will Shields Kansas City Chiefs, 1993-2006 Guard Greatest moment Shields will forever be known as a Chief, with his dedication to the team for 14 years, and among one of the best guards to ever play. He started 223 consecutive games and went to 12 Pro Bowls. In a career highlighted by paving routes for running backs, perhaps his best feat is helping anchor a line that in 1994 yielded 19 sacks, a team record for fewest in a season. That year was Joe Montana's final season in the NFL. Impact on the game

There are many, many problems with the way the NFL handled deflate-gate, and one is pretty basic: The league never cared about the air pressure of footballs before hammering the New England Patriots. That was clear from the Wells report, when it came to light that the Indianapolis Colts told the NFL before the AFC championship game that they were concerned about the Patriots deflating footballs, and the NFL did absolutely nothing about it until it was brought to their attention again in the first half. If the inflation level of footballs was Absolutely Crucial To The Integrity Of The Game, they'd have done something other than shrug once they were notified. [ Yahoo Sports Fantasy Football: Sign up and join a league todayl ] And the NFL doesn't even really know how and if their footballs can deflate. In explaining the new procedures for marking air pressure of balls before a game (again, if this was The Biggest Deal In NFL History, the league wouldn't have waited 95 seasons to implement this procedure), Central Region supervisor of officials Gary Slaughter said footballs could have a slow leak and officials wouldn't know, according to the Pittsburgh Tribune-Review's Mark Kaboly. "These are man-made products,” Slaughter said, according to the Tribune-Review. “There is a bladder and a valve. We have all checked them for many years. Sometimes when you check the ball in the locker room right out of the box, there could be a problem. They could have a slow leak, and you wouldn't even know it at the time.” None of this is too mind-blowing, because it's clear the NFL knew practically nothing about footballs and their inflation levels before turning deflate-gate into the modern day Black Sox scandal. That an NFL supervisor of officials acknowledges that footballs are subject to losing air because they're "man-made products" lets you know there are other unanswered questions. How do footballs react in cold weather? Do some leak? Do some lose pressure normally during a game? These are all interesting questions that have never been looked at before. That didn't stop the NFL from deciding which evidence fit their punishment and hammering Tom Brady and the Patriots, but I'm sure the league will learn some of those answers now that they actually care enough about the issue to have a procedure in place to check it. - - - - - - - Frank Schwab is the editor of Shutdown Corner on Yahoo Sports.

In his 14th attempt, Arsenal manager Arsene Wenger finally beat Jose Mourinho, who is in charge of Chelsea. As a bonus, Sunday's 1-0 win in the English season curtain raiser also gave the Gunners the 2015 Community Shield trophy. Alex Oxlade-Chamberlain got the game's lone tally in the first half. There would be no handshake after the game, with neither manager looking interested in acknowledging the other with the traditional postgame congratulations. At length, Wenger vanquished his longtime foe, with whom he's had a tense relationship for years. The managers could hardly be more different in their style and comportment. Wenger is professorial, studying his craft and tinkering with his formulas. Mourinho is more the self-taught street fighter, cheeky and provoking and scrappy. Wenger, as ever, wore a suit. Mourinho showed up in a T-shirt and track pants. But if their differences remain striking and fascinating, it was a transaction they cooperated on this summer that seemed to have made the biggest impact on the game. After a decade of first-team duty for Chelsea, and then agreeing to stay on another year as Thibaut Courtois's backup, Mourinho let his goalkeeper Petr Cech leave for Arsenal this summer as a kind of courtesy for his service and loyalty. [Premier League: Scores and Schedule | Current Standings | Teams ] Cech exuded a rare calm in Arsenal's box, where he was preceded by a seemingly endless series of flappers and blunderers. Wenger never quite managed to adequately replace David Seaman, who left in 2003 and actually was no stranger to the occasional howler himself. In Cech, he might have an answer at long last. In a chippy game, Chelsea mostly made the play and tried to locate the seams in Arsenal's back line, but there weren't many to be found. The Gunners, in turn, would counter with swashbuckling breaks. It was on one such play in the 24th minute that Theo Walcott found Oxlade-Chamberlain on the right side. He cut inside on defender Cesar Azpilicueta and deposited his finish into the far top corner with a splendid, left-footed finish. Arsenal hadn't scored against Chelsea in 506 minutes of play. More than 5½ games. . @IanWright0 heaps praise on @Alex_OxChambo 's superb finish against @thibautcourtois . #CommunityShield http://t.co/HXnFwQYKfv — BT Sport Football (@btsportfootball) August 2, 2015 At the other end, Arsenal's back line proved ever so solid. With Cech behind them, the Gunners gave up few chances. Ramires nodded a Loic Remy cross wide from a promising spot. Falcao spun away from the defenders and into the path of a long ball but was closed down well. Eden Hazard was put under sufficient pressure to smash a good look high. And the Belgian's free kick was later pushed out of the top corner by Cech. Arsenal fans seemed to quickly formulate hope that with such a big piece finally laid into the gaping hole in the puzzle, they might finally win the Premier League again. They haven't since the year after Seaman left, in 2004. But the last four winners of the Community Shield didn't go on to win the league. Indeed, after Arsenal hammered Manchester City 3-0 in this game a year ago, they placed third, a dozen points back from Chelsea and four behind City. If there's any point at all to this mostly symbolic game, though, it's to lend credence to a potential title-winning campaign for the winners – or, conversely, for the losers to write it off as a glorified friendly. Arsenal fans will feel confident after Sunday. Chelsea fans won't feel much of anything. Leander Schaerlaeckens is a soccer columnist for Yahoo Sports. Follow him on Twitter @LeanderAlphabet .

Before you commit to anything, be sure to double check the lineups and weather . Now go assemble your Yahoo DFS monster , make us proud. Jaime Garcia, SP, vs COL (Flande), $45: Although he’s the biggest Vegas favorite on the Sunday card, Garcia is merely the No. 8 pitcher in Yahoo price. Some might be a little concerned about Garcia after a layoff, though he did turn in a quality start on July 28. His overall ratios are excellent (2.00/0.89), and everyone knows the Rockies aren’t as much fun on the road. Noah Syndergaard, SP, vs. WAS (Zimmermann), $52: Sure, it’s a pay-up price, but the Baby Faced Ace known as Thor has ungodly powers at home (1.46 ERA, 0.79 WHIP, six walks, 51 strikeouts). That’s going to work. So long as you have John Kruk on mute, you'll have some fun on Sunday night. Buster Posey, C, at TEX (Perez), $19: You’ll need to get lineup confirmation, as we don’t know the San Francisco plan at press time. But with Posey on a monstrous tear and in a fun offensive park like Arlington in midsummer, I want in. Although Posey is the highest backstop on the board, the price isn’t all that prohibitive - it works down gradually, to the point that 18 other backstops are still at least two-thirds of the Posey cost. This is a round-about way of saying Posey’s not priced where he could be or perhaps should be. The Giants figure to be one of the highest scoring teams on Sunday, and Posey should have a piece of it. Ryan Howard, 1B, vs. ATL (Teheran), $16: The Phillies sold everything they could before the trade deadline, but Howard’s contract and diminishing production made him hard to move. Alas, he’s picked up his game this week, having some fun (12-for-26, two homers, 12 RBIs ) with the surging Phillies offense. Julio Teheran has been a mess on the road this year (7.24 ERA), so if you want to assemble a miniature Phillies stack, I’m on board. Kolten Wong, 2B, vs. COL (Flande), $15: Wong is merely the No. 9 second baseman in price, though he’s now the No. 3 hitter in the St. Louis lineup. Mediocre reliever Johan Flande is getting a shot in the Colorado rotation, but this sounds like a bullpen game for the Rockies to some extent. Advantage, Cardinals. [ Yahoo Sports Fantasy Football Pro Leagues are open: Sign up today! ] Jean Segura, SS, vs. CHC (Richard), $14: He’s batting .306 against southpaws, and he’s at home in a run-friendly park and against an ordinary pitcher. No wonder the Cubs wanted to upgrade the back end of their rotation. Evan Longoria, 3B, at BOS (Miley), $17: He’s not such a big deal in seasonal any longer, but he still has a pretty .911 OPS against lefties. Smile, you’re at Wade Miley’s, and you’re at Fenway Park as well. Eddie Rosario, OF, vs. SEA (Iwakuma), $14: He may not be the smoothest criminal out there (he’s been caught five times in 14 attempts), but at least he keep trying. More of interest is a hot homestand, which included three homers earlier this week. Rosario is batting .364 at home, and posted an .841 OPS in July. Jay Bruce, OF, vs. PIT (Morton), $19: The game of Charlie Morton is to keep you in the infield (all that Ground Chuck stuff), but Bruce likes the tilt of this matchup. Over 27 career at-bats, the lefty swinger has a .704 slugging percentage. He’s also having fun at home, with a .901 OPS this season. Khris Davis, OF, vs. CHC (Richard), $13: He isn’t as much fun as the other Chris Davis, but he now has a gig to himself with the Brewers moving outfielders. Milwaukee is a fun spot for a right-handed hitter on Sunday, up against a journeyman like Clayton Richard. Have a slide, Bernie Brewer.

New Toronto Maple Leafs general manager Lou Lamoriello had his first big contract test with Jonathan Bernier. Well, his first big test with his new team. In the arbitration hearing, Lamoriello shot waaaaay low. Bernier shot high with their asking prices. And in the end, both ended up settling on their own terms for two years at $8.3 million, which comes to $4.15 million per-year . The Leafs asked for $2.89 million in the arb case, while Bernier went for $5.1 million. The hearing took place Friday. Fair? Not fair? He had a 2.87 goals against average last season. He had a .912 save percentage. But the Maple Leafs were horrible. As Sportsnet’s Chris Johnston notes, this isn’t exactly ‘break the bank’ money. This is the 24th largest salary cap hit amongst goaltenders in the NHL. His prior contract was for two years at $5.8 million. [ Yahoo Sports Fantasy Football: Sign up and join a league today! ] The Maple Leafs also filed for arbitration on Bernier, and not vice-versa, so the thought was such a hearing would give Toronto more leverage. Maybe that wasn’t as much of the case? If the arbitrator ruled, it would have been for one year – and Bernier would have been an unrestricted free agent next summer, rather than in two years. Regardless, Bernier now gets two years to prove that he’s a legit starter – which is kind of mind blowing for a guy who is 26. And if Bernier finally shows his prodigious talent that made him the No. 11 overall pick in the 2006 draft – he also had a .923 save percentage with the Leafs in 2013-14 – then Toronto has a steal on its roster. Or at least a moderately priced trading chip if a contending team needs a goaltender off a rebuilding group. And then Bernier can cash in on UFA status in two years. So really, when you get down to it, this is a pretty decent deal for all parties involved. Maybe that Lou does know what he’s doing after all. - - - - - - - Josh Cooper is an editor for Puck Daddy on Yahoo Sports. Have a tip? Email him at puckdaddyblog@yahoo.com or follow him on Twitter!

Shutdown Corner is previewing all 32 teams as we get ready for the NFL season, counting down the teams one per day in reverse order of our initial 2015 power rankings. No. 1 will be revealed on Aug. 8, the day before the preseason begins with the Hall of Fame Game in Canton. NO. 7: BALTIMORE RAVENS In this offseason of regret, most of the focus has been on the Green Bay Packers and Seattle Seahawks, who blew playoff games in heartbreaking fashion. But don't forget about the Baltimore Ravens. The Ravens didn't flub an onside kick or throw an interception when they should have been running from the 1-yard line, but that doesn't lessen their pain. Twice they held a 14-point lead over the New England Patriots in a divisional playoff game. The Patriots played incredible football down the stretch to barely pull off the win. Two games later, the Patriots won a Super Bowl.

Dr. Saturday’s will unveil its preseason Top 25 team-by-team during the next 25 days. This list is based on returning starters, schedule and prospects. However, we all know that once the games begin, things can change very quickly. Still, we thought we’d give our best guess heading into the 2015 season. No. 24 Boise State 2014 record: 12-2, 7-1 Mountain West Returning starters: 9 Offense; 8 Defense 2015 Outlook: Coach Bryan Harsin’s first season could not have gone any better. The Broncos blazed through most of their schedule (sans a surprising loss to Air Force), won the Mountain West Mountain Division, won the conference title game, became the highest-ranked Group of Five team in the country and went on to defeat Arizona in the Fiesta Bowl. But this year, there will be a few challenges. [ Yahoo Sports Fantasy Football: Sign up and join a league today! ] Quarterback Grant Hedrick and running back Jay Ajayi, who accounted for 89.1 percent of Boise State’s yards and 92.4 percent of the offensive touchdowns, are gone, leaving the Broncos to plug those holes. However, there are nine starters returning to an offense that ranked 14th in the country in total offense (494.3 yards per game) and ninth nationally in scoring offense (39.7 points per game). Defensively, Boise State should be stout even if the numbers might not reflect that. The Broncos got into some track meets last year while allowing 26.8 points per game. Even though this defense should be better, the Mountain West is a high-scoring conference and the inflated numbers shouldn’t change much. Still, the Broncos best and most experienced playmakers are probably on the defensive side of the ball. As shocking as it sounds, Boise State can be better than a year ago and an undefeated season is a strong possibility. It opens the year against Washington and former coach Chris Petersen, which is a winnable statement game at home. Outside of BYU the following weekend, there are few challenges on what appears to be a pretty favorable schedule. Look for the Broncos to once against represent the Group of Five in a New Year’s Eve bowl. Player to watch: Tanner Vallejo, LB Vallejo had a historic season last year. He had 100 tackles and 16.5 tackles for loss, which was a Boise State FBS record. He was named the MVP of the Mountain West Championship game and the Fiesta Bowl. And he did all of this while playing outside his natural position. Vallejo spent the bulk of last season at nickel (strongside linebacker) because iof injuries to other players, but this year he moves back to middle linebacker, his favored spot. That puts him closer to the football and poised for an even bigger season. Vallejo is one of 10 returning starters on a defense that is loaded with talent. If there was one problem with Vallejo playing out of position, it was the propensity to give up the big play. But he should have more help on the outside this season with players returning from injury. Breakout player: Ryan Finley, QB Finley, a redshirt sophomore, is the only quarterback on the Boise State roster with experience and while he hasn’t officially been named the starter, he’s the favorite to win the job. He had limited experience in five games last year, mostly in a loss against Air Force after Hedrick was pulled following four picks in the first half. For the season, Finley completed 12 of 27 passes for 161 yards with two touchdowns and one interception. Don’t expect the Boise State offense to change too much with Finely under center. It was pretty balanced a year ago and, with Jeremy McNichols likely filling the running back role, should be again. Eliah Drinkwitz is the program's fifth offensive coordinator in six years, but he did lead Harsin's Arkansas State offense in 2013. The biggest obstacle for Finley this fall camp is gaining the trust of his teammates and staying on the good side of his coaches. Finley was arrested in April on misdemeanor charges of a minor consumption or in possession of an alcoholic beverage and resisting or obstructing police officers. He’s due in court in late September, but Harsin said during Mountain West media days that Finley has done everything he needed to get back into the good graces of the coaching staff and won’t face a suspension.

Ronda Rousey is quickly becoming one of the most iconic athletes in sports. On a night when many of the biggest superstars from sports and entertainment, including NBA stars Kobe Bryant and LeBron James, NFL star Aaron Rodgers, and actors Sylvester Stallone and Dwayne "The Rock" Johnson were tweeting to her to wish her luck, she rose to the occasion yet again. She needed only 34 seconds this time to retain her women's bantamweight title over Bethe Correia, but this wasn't the same old Rousey. Her striking, which some said was her weakness, led her to the one-sided victory in the main event of UFC 190 at HSBC Arena Saturday in Rio de Janeiro, Brazil. Rousey's striking overwhelmed Correia, whose striking had led her to a 9-0 mark entering the bout. But Rousey ripped Correia with clean, hard shots and finished it with a right to the temple. Correia fell on her face as referee John McCarthy quickly stopped it. It was four seconds longer than the combined time of her two previous wins -- 16 seconds over Alexis Davis at UFC 175 and 14 seconds over Cat Zingano at UFC 184 -- but in the manner of finish, it was probably her most impressive.
